Biodiversity And Conservation

The correct option is(C): (B) and (D) only.

(A) Species diversity does not necessarily increase as we move away from the equator towards the poles. The pattern of species diversity can vary depending on various factors such as habitat type, climate, and historical factors.

(B) The tropical Amazon rainforest in South America is known for having one of the greatest biodiversity's on Earth. It is home to an incredibly rich variety of plant and animal species.

(C) This statement is not correct. The tropics generally receive more solar energy compared to the temperate regions. The higher solar energy input in the tropics contributes to the warm climate and supports high levels of productivity, which in turn can support high biodiversity.

(D) This statement is correct. Tropical environments typically experience less seasonality compared to temperate regions. They have relatively stable and consistent climatic conditions throughout the year, which can provide a more predictable environment for species and contribute to the higher biodiversity observed in tropical regions.

The correct option is(C): Endemism.

The option "Endemism" is not a cause of biodiversity loss. Endemism refers to the ecological phenomenon where a species is restricted to a particular geographic region and is not found naturally anywhere else. It is a measure of uniqueness and diversity within a specific area, rather than a cause of biodiversity loss.
